Description
본 발명은 슬러지처리장치 관한 것으로서, 보다 상세하게는 컴팩트하고 간단한 구성으로 되며, 에너지효율이 높은 새로운 구성의 슬러지처리장치에 관한 것이다.The present invention relates to a sludge treatment apparatus, and more particularly, to a sludge treatment apparatus of a new configuration having a compact and simple configuration and high energy efficiency.
각종 폐수의 처리 후에 발생되는 슬러지는 함수율이 상당히 높은 묽은 죽상태이다. 일반적으로 이러한 슬러지는 먼저 탈수하여 함수률을 낮춘 다음, 매립하거나 소각처리한다. 그러나 슬러지 입자들이 물과의 친화력이 강하기 때문에 전술한 바와 같이 슬러지를 별도로 탈수처리하여도 수분함량을 소정수준으로 낮추기는 곤란하다. 따라서 슬러지를 매립처리하는 경우에는 슬러지가 오염물질을 다량 함유하고 있기 때문에 슬러지 자체가 토양을 오염시킬 뿐만 아니라 슬러지를 탈수처리한 후에 매립하더라도 슬러지에서 유출수가 발생되어 매립지의 주변 토양이나 수질이 오염된다.The sludge generated after the treatment of various wastewaters is a thin bamboo state with a very high moisture content. Generally, these sludges are first dehydrated to lower the water content and then landfilled or incinerated. However, since the sludge particles have a strong affinity with water, it is difficult to lower the water content to a predetermined level even if the sludge is dewatered separately. Therefore, when the sludge is landfilled, the sludge contains a large amount of pollutants, so the sludge itself not only contaminates the soil, but even when the sludge is dehydrated, the outflow water is generated from the sludge and the surrounding soil and water quality of the landfill are polluted. .
또한, 슬러지를 소각처리하는 경우에도 탈수처리하여 소각한다하더라도 슬러지의 함수율이 비교적 낮은 상태가 아니기 때문에 소각시 많은 에너지가 소요될 뿐만 아니라 슬러지의 내부까지 열이 고르게 전달되지 않아 슬러지가 불완전연소되면 대기를 오염시키는 질소화합물 등과 같은 오염물질이 발생되어 심각한 대기오염을 유발한다.In addition, even in the case of incineration of sludge, even though it is dehydrated and incinerated, the water content of the sludge is not relatively low, and thus a large amount of energy is consumed during incineration, and heat is not evenly transferred to the inside of the sludge. Pollutants such as polluting nitrogen compounds are generated, causing serious air pollution.
본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 구성이 콤팩트하고 간단한 구성으로 되어 제작이 용이하며, 슬러지 중의 수분을 무화시킨 후에 증발시키도록 되어 적은 에너지로 슬러지의 수분을 효과적으로 제거하도록 된 새로운 구성의 슬러지처리장치를 제공하는 것이다.The present invention is to solve the above problems, the object of the present invention is to be compact and simple configuration is easy to manufacture, to evaporate after atomizing the water in the sludge effectively remove the water of the sludge with less energy It is to provide a sludge treatment apparatus of a new configuration.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 1은 본 발명을 일 실시예를 보인 개략도이다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a schematic view showing an embodiment of the present invention.
본 발명은 폐수의 정화처리 후에 발생되는 슬러지의 처리장치로서, 가열챔버(10)와, 이 가열챔버(10)의 내부 전단부에 구비되어 버너(22)에 의해 가열되는 축열판(20)과, 상기 축열판(20)을 향해 슬러지를 고압분사하는 분사노즐(30)과, 상기 가열챔버(10)의 후단부에 구비되어 수분이 제거된 슬러지입자 또는 이 슬러지입자가 축열판(10)에 부딪혀 소각되어 생성된 분진 등을 포획하여 제거하는 싸이클론집진기(40)와, 이 싸이클론집진기(40)에서 제거되지 못한 미세분진이나 가스상물질을 ??터링하는 백필터(50)를 포함하여 이루어진다.The present invention is a sludge treatment apparatus generated after the waste water purification treatment, the heating chamber 10, the heat storage plate 20 is provided in the inner front end of the heating chamber 10 and heated by the burner 22 and , The injection nozzle 30 for spraying the sludge at high pressure toward the heat storage plate 20, and the sludge particles or the sludge particles having water removed from the heat storage plate 10 at the rear end of the heating chamber 10. It comprises a cyclone dust collector 40 for trapping and removing the dust generated by the incineration, and the bag filter 50 for filtering the fine dust or gaseous material that was not removed from the cyclone dust collector 40 .
상기 가열챔버(10)는 대략 좌우로 긴 통상으로 되어, 그 전단부에는 축열판(20)이 구비된다. 이 축열판(20)은 가스버너(22)에 의해 가열되어 대략 800℃이상의 온도를 유지하게 된다. 이러한 축열판(20)은 비열이 커서 축열성이 좋은 스텐레스나 세라믹소재 등으로 된다.The heating chamber 10 is generally long left and right, and the heat storage plate 20 is provided at the front end thereof. The heat storage plate 20 is heated by the gas burner 22 to maintain a temperature of approximately 800 ° C or more. The heat storage plate 20 is made of stainless steel or ceramic material having a high specific heat and good heat storage property.
그리고 상기 축열판(20)의 후방에는 슬러지를 축열판(20)을 향해 고압분사하는 분사노즐(30)이 구비된다. 이 분사노즐(30)은 폐수의 정화처리 후에 발생된 슬러지를 저장하는 저장탱크(29)와 연결된다. 따라서 상기 분사노즐(30)을 작동시켜 축열판(30)에 슬러지를 고압분사하면 슬러지가 축열판(30)에 부딪히면서 슬러지의 수분 중 일부는 증발되어 기화되고, 나머지 일부는 축열판(30)에 부딪히는 충격력에 의해 슬러지입자와 분리되어 무화된다. 그리고 이때 축열판(20)이 고온으로 가열된 상태이므로 슬러지와 분리되어 무화된 수분은 축열판(30)의 열에 의해 기화된다. 이때 상기 축열판(22)은 전술한 바와 같이, 대략 800℃ 이상을 유지하는데, 축열판(22)의 온도가 높을수록 수분의 무화가 더욱 효과적으로 이루어진다. 이와 같이 축열판(20)에 부딪히는 충격력에 의해 슬러지입자와 분리되어 무화된 수분은 축열판(20)의 열에 의해 기화된다. 그리고 수분이 분리되어 가열된 슬러지는 상기 축열판(20)의 열기에 의한 가열챔버(10) 내의 공기흐름에 의해 가열챔버(10) 내의 후방으로 이송되는데, 이때 가열된 슬러지입자 중의 일부는 축열판(20)에 부딪혀 소각되기도 한다.And the rear of the heat storage plate 20 is provided with a spray nozzle 30 for high-pressure spraying the sludge toward the heat storage plate (20). This injection nozzle 30 is connected to a storage tank 29 for storing sludge generated after the purification of waste water. Therefore, when the injection nozzle 30 is operated to pressurize the sludge onto the heat storage plate 30, the sludge hits the heat storage plate 30 and some of the water in the sludge is evaporated and vaporized, and the other part is stored in the heat storage plate 30. It is separated from the sludge particles by the impact force to be atomized. At this time, since the heat storage plate 20 is heated to a high temperature, moisture separated from the sludge and vaporized is vaporized by the heat of the heat storage plate 30. In this case, as described above, the heat storage plate 22 maintains approximately 800 ° C. or more, and the higher the temperature of the heat storage plate 22 is, the more effectively the atomization of moisture is achieved. In this way, the water that is separated from the sludge particles by the impact force striking the heat storage plate 20 and atomized is vaporized by the heat of the heat storage plate 20. And the sludge heated by separating the water is transferred to the rear in the heating chamber 10 by the air flow in the heating chamber 10 by the heat of the heat storage plate 20, wherein some of the heated sludge particles are heat storage plate (20) may also be incinerated.
이와 같이 하여 가열챔버(10)의 후방으로 이송된 슬러지입자와 이 슬러지입자가 소각된 재로 이루어진 분진은 상기 싸이클론집진기(40)에 포집되어 제거된다. 이때 상기 싸이클론집진기(40)의 배출구(42) 하측에는 이송컨베이어(44)를 설치하여 포집된 분진을 외부로 용이하게 반출시킬 수 있도록 한다. 그리고 상기 싸이클론집진기(40)에서 제거되지 않은 미세한 분진이나 가스상물질은 싸이클론집진기(40)의 상측에 구비된 백필터(50)를 통과하면서 제거된다. 한편, 이때 기화된 수분에 의해 가열챔버(10) 내의 습도가 상당히 높은 상태이므로 백필터(50)의 효과가 다소 저하될 우려가 있다. 따라서 백필터(50) 내부의 온도를 소정수준으로 유지하여 기화된 수분이 응결되지 않고 기화된 상태로 백필터(50)를 통과하도록 함으로써, 수분에 의해 백필터(50)가 막혀 필터링효과가 저하되지 않도록 한다.In this way, the dust composed of the sludge particles transported to the rear of the heating chamber 10 and the ash in which the sludge particles are incinerated is collected and removed by the cyclone dust collector 40. At this time, the transport conveyor 44 is installed below the outlet 42 of the cyclone dust collector 40 so that the collected dust can be easily taken out to the outside. The fine dust or gaseous material not removed from the cyclone dust collector 40 is removed while passing through the bag filter 50 provided on the cyclone dust collector 40. On the other hand, since the humidity in the heating chamber 10 is considerably high due to the vaporized water, the effect of the bag filter 50 may be slightly reduced. Therefore, the temperature inside the bag filter 50 is maintained at a predetermined level so that the vaporized water passes through the bag filter 50 in a vaporized state without condensation, whereby the bag filter 50 is blocked by moisture and the filtering effect is reduced. Do not
또한 바람직하게는 상기 백필터(50)의 배출구에는 탈황장치(60)와 같이 배출가스 중에 포함된 특정의 유독성분을 제거하는 정화장치를 구비하여 배출가스에 의해 공기가 재오염되는 것을 방지한다.In addition, the outlet of the bag filter 50 is preferably provided with a purifying device for removing specific toxic components contained in the exhaust gas, such as the desulfurization apparatus 60 to prevent the air from being recontaminated by the exhaust gas.
이상에서와 같이 본 발명에 의하면, 콤팩트하고 간단한 구성으로 된 새로운구성의 슬러지처리장치가 제공된다. 이러한 본 발명에 의한 슬러지처리장치는 축열판에 슬러지를 고압으로 분사하여 슬러지의 수분을 무화시킨 후, 무화된 수분을 증발시키는 것이므로 종래의 소각기와 같은 열처리장치에 비해 에너지소비량이 절감되어 효율적이다. 필요에 따라서는 이러한 본 발명을 분유 등과 같은 식품의 가열시에 사용하면 적은 에너지로 식품을 용이하게 가열시킬 수 있을 것이다.As described above, according to the present invention, a sludge treatment apparatus of a new configuration having a compact and simple configuration is provided. The sludge treatment apparatus according to the present invention sprays the sludge at a high pressure on the heat storage plate to atomize the water of the sludge, and then evaporates the moisture of the sludge, so that the energy consumption is reduced and efficient compared to a heat treatment apparatus such as a conventional incinerator. If necessary, when the present invention is used for heating a food such as powdered milk or the like, it will be possible to easily heat the food with little energy.
